The cumulative probability of multiple live birth is presented. The overall cumulative live birth rate in our study population of more than 10,000 patients is presented in (A). The cumulative live birth rate is stratified by patient age at the start of the first fresh, nondonor IVF cycle. This rate is presented as the cumulative singleton live birth rate (B) and the cumulative multiple live birth rate (C).
